If you’re starting to wrap presents for the holidays, you might want to hold on to those long cardboard wrapping paper tubes. With a few other household materials you can make an effective draft blocker for under your door.

In this video from youtuber DaveHax, you’ll learn all kinds of helpful tips for keeping warm this winter. You’ll learn the basics of staying warm, as well as how to make your own radiating heater with some tealight candles, and last but not least, a great way to block drafts under your door. Grab an old pair of tights, stockings, or leggings, cut off one of the legs, and stuff two long wrapping paper cardboard tubes inside. Then just slide the whole thing under the door. Now you have an extra incentive to get your presents wrapped early this year! If you don’t any of those materials, you can also make a draft blocker with a pool noodle or some pipe insulation.
